ARA

Overview

The Ecorobotix ARA is a solar-powered autonomous precision spraying robot designed to dramatically reduce herbicide and pesticide consumption through hyper-targeted application. Developed by the Swiss company Ecorobotix and priced at approximately $60,000, the ARA uses an array of cameras and AI vision to identify individual plants across a field, distinguishing crops from weeds in real time. It then applies micro-doses of treatment directly to target plants, using up to 95% less chemical input than conventional boom spraying.

Key Specifications

• Operating speed: 6 km/h
• Runtime: 12 hours (solar-assisted, with supplementary battery)
• Spraying precision: Individual plant targeting, micro-dose application
• Coverage: Approximately 10 hectares per day depending on crop density
• Price: Approximately $60,000

The ARA's solar panels provide continuous daytime energy input, extending operational time well beyond standard battery-only platforms. The robot operates autonomously across the field width (up to 6.5 m span) and can treat crops including sugar beet, vegetables, and inter-row arable crops.

Use Cases

In the UK context, the ARA is relevant for vegetable growers, sugar beet producers, and arable farmers under pressure to reduce chemical inputs. The shift away from neonicotinoids and growing herbicide-resistance challenges in UK arable farming make precision application technology economically attractive. For a 500-hectare arable farm, the reduction in active ingredient cost alone can generate a meaningful return on the capital investment within two to four seasons.

The ARA integrates with farm management information systems (FMIS) and generates application maps for traceability, which is increasingly relevant for assured supply chain requirements.

Buying Used

A small secondary market exists for ARA units, primarily via European agricultural machinery dealers. Because the robot's software and AI models are maintained via Ecorobotix cloud updates, any used unit should be verified for active software support before purchase. Ecorobotix has a distribution presence in the UK market.

Alternatives to Consider

• Small Robot Company Tom and Wilma for a UK-native per-plant approach combining scouting and weeding
• Naïo Technologies Oz for inter-row mechanical weeding without chemical application
• Carbon Robotics LaserWeeder for thermal weed control as an alternative to chemical treatment
